HOSE-COUPLING;

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed. February 6, 1909. Serial N o. 476,377.

T o atl rwhom it may concern.'

Be it known that I, VINonN I. MCVOY, a citizen of the United States of America, and resident of Mobile, in the county of Mobile and State of Alabama, have invented certain new and useful Improvements in Hose-Couplings, of which the following is a specication.

The present invention relates to hose couplings and more particularly to that class known as quick-acting and in which two opposed sections have interlocking or engaging parts, a partial revolution of which only is necessary in order to accomplish the coupling, or, by a reverse motion, to uncouple.

The present invention has for its objects among others to provide a simple andimproved, yet durable and efficient coupling composed of few parts and those readily assembled and actuated.

It has for a further object to provide simple and efficient means for preventing accidental retrograde movement of the parts when once coupled.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which- Figure l is a side elevation showing two sections of hose connected by my improved coupling. Fig. 2 is a substantially central longitudinal section through the coupling membersin coupled position. Fig. 3 is a view looking at the inner end of one of the coupling sections. Fig. 4 is a similar view showing a diiierent disposition of the parts. Fig. 5 is a side elevation of a slightly modified form of construction. Fig. 6 is an elevation on an enlarged scale showing the members of the two coupling sections separated but in their relative positions. Fig. 7 is an elevation, also on an enlarged scale, showing the two coupling sections ready for coupling.

Like numerals of reference indicate like parts in the several views.

As the coupling sectionsV are alike in all respects, a detailed description of one will suflice for both.

Referring to the drawings, l designates the body portion or interior member of the one section, It is formed with the annual band portion 2 and the reduced annular portion 3. At the end opposite the reduced portion 3 is an annular groove 4, the outer wall of which is formed by the inner walls of the lugs 5, in this instance two in number and diametrically oppositely disposed, each lug extending substantially a quarter of the circumference of the member, leaving the spaces 6 between adjacent ends thereof, as seen clearly at the right of Fig. 6. These spaces merge into the groove Il, as will be clearly understood upon reference to said Fig. 6. The ends of the lugs 5 are rounded or tapered, as shown at 7, to facilitate engagement of the parts when the sections are coupled together. Itis to be noted that the lugs 5 have their outer faces substantially Hush with the outer periphery of the band 2, which not only increases the strength but permits of the application of the member which embraces the body portion from the lug end. This permits of the entire separation of the parts of the coupling member for repairs or other purposes without disconnection of the hose from the body portion. The end of the member 1 adjacent the lugs 5 is formed with a groove or gasketreceiving socket 8 in which is retained a gasket 9 of any suitable character, the said groove or' socket being preferably undercut, as seen infFig. 2, whereby the gasket may be retained by frictional engagement of the parts, although this frictional 'retention may be supplemented by cement or other suitable means, if desired.

The annular band 2 of the member 1 is provided with a threaded opening for the reception of a screw or pin 10, the function of which will soon be described.

The member'l is formed at its inner end with an internal annual shoulder 11 which forms the backing for the gasket, as will be readily understood upon reference to Fig. 2.

By reason of the lugs 5 having their peripheral face flush with the outer face of the'band 2I of the member 1, I am enabled to reduce the diameter of the coupling the thickness of the lugs which reduces the weight without decreasing the strength of the coupling member.

12 is the member coperating with the body portion l and adapted to embrace the same. It is formed with the circumferential screw threads 13 interrupted by the `annular groove 14 which extends entirely around the same, which forv substantially one-half of its diameter is cut away entirely l thro-ugh the body portion of the member to form a substantially semi-circular slot 15, the object of which will soon be made apparent. Adjacent the inner end of the threaded portion is an annular shoulder 16, from which extend the lugs 17, in this instance two in number, diametrically oppositely disposed, and each extending` substantially a quarter of the circumference of the member. This, of course, leaves spaces 1S at diametrically opposite points between adjacentrends of the two lugs. These lugs 17 are formed at their outer ends with the inwardly extending flanges 19, seen at the right of Fig. 6, which, of course, leaves the larger diameter 2O beyond the same, which diameter is the same as that of the band 2 of the body portion 1.

21 is a tightening and locking ring. It is formed with a roughened or milled periphery, as seen at 22, for an obvious purpose, and at its outer end is rounded, as seen at 23, so as to avoid abrupt shoulders, thus facilitating the drawing of the hose over the ground, out of wagons, through buildings etc. The milled periphery is provided with a screw hole 241 for the reception of a screw 25, as will be hereinafter explained. This ring is internally threaded, as seen at 26, to engage the threads 13 of the member 12, and at its outer end with an inwardly extending annular shoulder 27, as seen clearly in Fig. 2.

The lugs 17 may be parallel sided, as seen in- Fig. 1, or they may be tapered, as seen at 28 in Fig. 5, to facilitate interengagement of the parts. lVhile in Figs. 1, 2, 3, t, 6 and 7 I have shown the sections as provided each with two lugs, it is evident that this number may be varied; for example, as seen in Fig. 5, this number may be materially increased.

In assembling the parts, the members 1 and 12 may be engaged by inserting the member 1 in the member 12, with the lugs 5 coincident with the spaces 18 of the member 12. The parts are then moved upon each other in the direction of their length until the lugs 5 are in line with the grooves 20.

Then, by partial rotation of the parts, the lugs 5 are brought coincident with the inwardly extending flanges 19 of the member 12. Opening for the screw 10 in the band 2 will then be coincident with the slot 15 between the screw threads of the member 12 and then the screw 10 is affixed in position. This allows the member 12 to have rotary motion with relation to the member 1 but the engagement of the screw or stop member 10 with the shoulders 29 formed at the ends of the slot serves to limit the rotary move ment of members with relation to each other. This screw or stop member 10 also serves, by engagement with the opposite walls of the slot, to limit the movement of the members endwise with relation to each other in one direction, movement in the opposite direction being limited by the shoulder 30 at the junction of the band 2 and the reduced portion 3 of the member 1. As will be seen in Fig. 2, the slot 14 is of greater width than the diameter of the screw 10 so as to permit of this limited endwise movement of the parts. These two parts having been thus assembled, the tightening and locking ring 2l is applied over the end of the member 1, as seen in Fig. 2, its threads being engaged with the threads 13 of the member 12 and, when sufficiently screwed up, the screw 25 is applied, the inner end of which works in the groove 14 of the member 12, in line with and over or outside of the stop member 10, as will be clearly understood upon reference to Fig. 2, the ring thus having rotary movement upon the threaded portion of the member 12 but limited in both directions, in or out, by engagement of the screw with the opposite side wall of the groove, the movement, however, being sutlicient for all necessary endwise movement of the locking ring. With the members of the two sections assembled as above described, the parts are ready for coupling, it being understood that one section is secured to an end of the opposing lengths of hose 31. The parts of each section are turned so that the lugs are coing cident with the projections 2O and behind the inturned ianges 19 thereof. The two sections are then brought together with the projections of one coincident with the spaces between the projections of the other. Then a partial turn of the sleeves or members 12, either to the right or the left, causes the interlocking of the lugs, which interlocking, it will be understood, is double and that, when in this position, the parts are interengaged so that endwise movement is prohibited. Then turning up of the tightening and locking ring serves to securely retain the parts in such position so that it is impossible to uncouple without first slaclrening up the tightening and locking ring, or both rings, should both have been tightened (although tightening of one is suiiicient to secure the parts and insure a water-tight joint), and turning of the men'ibers 12 in the reverse direction to that in which they were turned to couple. The parts may be then separated by endwise movement. The parts cannot be turned too far in either direction, being limited by the engagement of the pin or screw 10 with the shoulders 29 of the slot As the tightening and locking ring is turned up, the inner-wall of its inturned `flange 27 engages with tlie shoulder 30 of the member 12, as will be seen in Fig. 2.

It will be noted that the parts are prol projections, leaving the coupling without abrupt shoulders, thus adapting it for easy manipulation, in taking out of wagons, dragging over the ground or through houses and the like.

In order to better insure against retrograde movement of the parts when coupled, I may serrate theA inner faces of the lugs 5 and the inner faces of the inturned ianges 19 of the projections 17, as seen clearly at 32 in Figs. 6 and 7, so that, as the parts are turned up, the interengagement of these teeth or serrations effectually serve to prevent retrograde movement of the parts.

The annular band member 33 between the projections of the sleeve members serves to receive any impact occasioned by dropping of the coupling on the ground and protects the locking rings from injury.

Modications in detail may be resorted toA without departing from the spirit of the invention or sacrificing any of its advantages.
